LEJ is your provider of high-performance Illumination as well as Power Electronic solutions in the fields of Microscopy, Analytics, Semiconductor, Industry and Medical Technology.
Besides its comprehensive portfolio of standard products LEJ offers the highest degree of flexibility and speed to bring customer-/application-specific products to the market. World-known OEMs count on LEJ as their system provider for e.g. microscopy illumination, electronic assemblies for spectroscopy, laser and system power supplies, LED high performance controller as well as their partner for contract assembly of complex opto-mechanical and opto-electronical sub-assemblies and systems.
With LUXYR and AMPYR LEJ markets two proprietary-developed lines of standard products, utilized specifically in microscopy applications. Especially in demanding Fluorescence, but also in routine Transmitted and Reflected Light microscopy applications the Xenon, Mercury and LED light sources (broad-band, multi-channel) are employed worldwide.
The entire range of products can be customized according to customers and applications. By providing a modular design as well as an intelligent roadmap-based development platform, LEJ allows such customization to be conducted in a very short time (time-to-market) and at reasonable costs.
LEJ supports OEM customers with in-depth know-how in dimensioning Lamp-, LED- and (increasingly) Laser-powered Illumination Systems. LEJ is in the unique position to advise customers independent from the light sources, thus being able to develop and manufacture hybrid / multi-modal Illumination Solutions. In the field of Power Electronics customers benefit from durable, productive, long term available solutions that, at the same time, deliver reproducible and quantifiable results.
Leistungselektronik JENA GmbH (LEJ) was founded as a spin-off of the research center of Carl Zeiss Jena GmbH in December 1991. The company is fully vertically integrated with a strong focus on core technology competencies, all manufacturing facilities are DIN ISO 9001 certified and NRTL supervised to ensure an invariably high standard of quality and reliability of our products.
